Currently Amazon has a SeaSonic Focus Gold 650w for $62. Quite a good deal given current market.

Do you think that could handle a 990x+590?

I would like 750w but that's like $45 more and my wallet would not like that.

I have not had the opportunity to really load it on the Segotep kind of because I am scared.
 
For someone to sell any kind of Seasonic Gold unit for $62, and turn any kind of profit from the venture, they need to have gotten it originally at less than half the asking price. Tell me where a Seasonic can be found for less than $30 new.
 
I have looked at reviews and while it certainly isn't their best unit, it seems pretty decent? It is also recommended on the first page of this thread.

From Aris's review of the 750w version:
EVGA's 750 GQ offers decent performance with the only exception being the increased ripple on the minor rails. It is priced competitively and has high efficiency, but it lacks silent operation; however, at light loads the PSU's passive operation saves the day.

I don't care about silent operation, a pc with a GTX590 and extreme edition, all air cooled, is not going to be quiet anyhow. As long as the ripple isn't out of spec that shouldn't be an issue either?

Somehow, the 600w Segotep won't flinch with both 580s and the 990x running at 100%, so I don't think this GQ is going to have any issues.

I saw the Leadexiii going on sale but it only ended up being like $5 off, and well over 100 bucks in 750w form.

EVGA had a lot of decent deals last night. They had bstock EVGA BR450 bronze units for $17.99, but they sold out before I could checkout. Was going to buy one for my nas which could use an efficiency boost from the current non 80+ oem unit.

I also got a GD600w for $35. I think this is the FSP based one so not a fantastic unit either, but good as far as $35 PSUs go. I have a use for it in the upcoming future.
 
I was looking for a review of the GQ850w and couldn't find one. I checked the LTT PSU tier list spreadsheet to see if they had any reviews linked, sorry to bring it up, but It sparked a question I hope someone can answer.

The GQ850w+ is tiered higher than the 750w and below, so I am assuming there are some changes to the higher wattage units? As is often the case there is no proper citation or review of a higher wattage unit backing up this difference/tiering, but I am wondering if anyone has a clue if there is a difference?

I can't find a review of the 850w to see if its any different. One thing I noticed was the GQ850w is much longer than the GQ750w.
 
Wasn't about the list as much as it was a question about the unit generated by looking at the list sources. Don't feel like opening any cans of worms, just mentioned that's what sparked my question.

I am guessing that the 850w is indeed different because that review said the ripple was excellent on all rails, but Arris complained about the ripple with the 750w.

I don't see any problems with this unit or why it isn't very good. That review said it was a fantastic performer...

Any recommendations for dual system psu? I can fit only one psu :/ The phanteks revolt X is out of the question since too expensive and I only need 850W of power and read that it has a lot of problems. Is there any similar psu-s to that? Anyone knows how to get phanteks power splitter?

Yeah just look at the comments. Not a single one about the psu question or just any help at all. Just commenting irrelevant things while it looks like they don't understand why is good to have a dedicated streaming PC.

A dedicated streaming pc can be a good idea for some people.
Your issue is that dual setup inside a single case.
You'd be far better off (both system wise an financially) build a single gaming rig then a seperate matx setup for streaming.

That phanteks (from what I see) is about the only option psu wise without running a second psu outside of the case, it's a stupid amount of money to be spending for that sole purpose.

Agree.

There are plenty of dual-system PC cases out there. Though, biggest issue is wanting to have only one PSU and not wanting to hand out premium price for Phanteks Revolt X PSU, which is only PSU of it's kind that can power two systems at once. Phanteks Power Splitter is another option but it's ordeal to find one.
 
The EVGA GQ850w is working great so far. As usual, I am extremely impressed with EVGA Bstock as the unit looks brand new, completely spotless.

I was very surprised by how thick the AC lead it came with was, but makes sense. 🤣

I do have a couple of complaints about this unit though. One main one is the length of the EPS connector is not very long. It reached to the connector but not much slack for cable management. The NZXT S340 isn't an unusually large case either, and it was quite a common case not that long ago.

Additionally, I have found I really dislike flat cables commonly found on modular PSUs. Luckily the GQ has a fixed and sleeved 24 pin, unlike some of my other PSUs. I find these cables harder to cable manage and zip tie since they are not round.

I much prefer the sleeved black cables on my GD600w, which I picked up for $35 the same day. That unit looks sorta gutless inside, but seems okay component quality wise, excluding the yate loon fan.
 
Anyone have an opinion on Refurbished Power Supplies? I'm looking at this Corsair RM 650 Watt, 80+ Gold, for a nice $89.99. However, I'm concerned that if get a bad PSU, it could damage other new components in the system. Or is the likelihood of that no higher than in a brand-new power supply?
 
If it's manufacturer refurbished, and comes with a warranty, then it's not significantly more likely to have an issue than it was when it was new. It will have been fully tested before being sent back out, but personally I'd never pay that kind of money for any piece of hardware that didn't come with a FULL warranty, and most refurbished hardware only comes with a short and limited warranty.

However, current times, are somewhat....................different, than normal, so you might have to do what you have to do in some circumstances.

I buy manufacturer refurbished PSUs quite often. Heck, the HX750i in my PC was a pull from a used PC from ebay.

Sometimes you can get a dud if buying used, but manufacturer refurbished units are tested working and shouldn't be an issue.

They will have some of their lifespan already taken up, so they might not be as long lasting, so keep that in mind.

Based on amazon link, it isn't manufacturer refurbished. Instead, it is:
This pre-owned product has been professionally inspected, tested and cleaned by Amazon-qualified suppliers.

For warranty period, it comes with 90 days.
For comparison, brand new RM650 comes with 10 years of warranty.

I wouldn't buy it.

Btw, brand new RM650 costs $126,
amazon: https://www.amazon.com/dp/B07RFZPN8G

Or you can go with Seasonic Focus+ 650 for $105,
