PSU tier list 2.0

[Karadjgne]

True, the higher wattage platforms like 1k and above are most usually Platinum rated, there only so much room in a ATX psu, so to get the higher outputs takes bigger/better components or you'd not be able to shove the current through. And I've yet to see anyone brave enough to spend the amount of money required for multiple gpus use a low grade, cheap high wattage psu. $1500+ for 2x gpus on a $30 psu? Not gonna happen.

Nah, guaranteed it'll happen and it'll show up on one of the threads here. Be like, "oh, why doesn't the PC boot!", and has like 2 Titan Xp's using a $5 350W Bestec. 2nd Law of Thermodynamics, you know.

Rofl. Just answered a post, Op wanted to stick sli 970s on a Lepa 650w. Forget the 2nd Law of Thermodynamics, think instead of Murphy's 1st Law of Reality.

I went with an EVGA that was recommended in tier 1... I found out the Quark has shorter Mobo 6 pin cables... my current Rosewill cables barely reach! So having shorter cables may cause trouble. Got a nova g2 750.

awesome man

 

[Karadjgne]

Very nice psu. Got nothing but good things to say about it.

 

[glytch5]

Thanks guys. Hopefully I won't get a dud! The main reason I want a new PSU is this one is quite loud... lots of cable wine and I want to overclock a bit more. Ryzen 7 just arrived at my door! ; )

 

[Valenicy]

is EVGA 650 GQ safe to use?

 

[superninja12]

gq is a decent unit, yes i dare to use it.

 

[Valenicy]

Can it fit in a mini tower case like corsair 400c or nzxt s340 elite?

 

[okcnaline]

Yes.

Hey guys! Would you help buying a new psu? My budget is 50~60$
My system specs:
Asus p5q-e (8-pin cpu power connector)
Q9650 (planning to push it to 4.0~4.5)
Rx 480
HyperX ddr2 4x 2GB @1000MHz 2.2v
3 sata 7.2k

FSP?

Thanks, okcnaline for replying! Forgive my ignorance, but what does "FSP" stand for?

 

[ko888]

The EVGA B3 models are made by Super Flower not FSP Group.

[Xsanchi]

Aha so FSP is a psu maker! Okay now which one should I go with? Is there any better choice?

The Antec one since that's been reviewed years ago. I don't know much about that new B3 unit yet.

 

[turkey3_scratch]

I suspect the B3 units to lower their quality from the B2 since their prices seem to be lower. A good idea, many people will just assume they're better than the B2.

Well, we don't know what platform it's based on. You suspect Leadex Silver, right? I found no info on that one.

 

[Karadjgne]

To be fair, the b3 also come in 450/550 /650/750/850 fully modular vrs the b2 750/850 semi modular, so prices per unit can be cut down as all those modular cables should be the same across the entire series. Bulk rates on those will cut costs vrs the proprietary cables on just 2 units. Manufacturing costs are also lower on a full modular unit, 1 chunk of plastic, solder it, move on vrs having to tap in and solder individual wires. You are also looking mainly at a unit designed to take on Corsair's CX/CXM, so prices will have to be somewhat equitable if not better, or you won't get the sales as most CX users are buying simply due to brand recognition at a low price and really have no clue (or care) as to quality, as long as it works and won't blow up like their prior OEM they overloaded. Seriously doubt that the b3's are lower priced because they are worse than the b2's.

If manufacturing is cheaper on fully modular what incentive would a company have to make a semimodular PSU?

 

[Karadjgne]

If you look at the full range of psus, all the wired, semi, they all use the same wires for mains, EPS, pcie. So you can get bulk rate wires much cheaper than limited production fully modular on just 2 or 3 units. But if you switch up, and concentrate on 5 units, all using the same connections, the price per unit goes down across the board, especially if those secondary connections are universal with what's already used on the semi modular. In time taken, it's faster by far to just slap in a plastic molex and solder it than have individual wires soldered one at a time. Which means more units per hour, which is lower cost. It cheaper per unit to pump out a b3 than it is a b2. It's only more expensive to make a full modular when you run proprietary connections like was done with the AX series having different plugs for different size units.

Now have you worked in the PSU or related industry where you know this for a 100% fact or are you applying your knowledge to other industries to this?

 

[Karadjgne]

Applying knowledge of other industries, most of which are related to electric, electronics, wiring, bulk orders, shipping/receiving, manufacturing, cost analysis. But not psus specifically, but components for industrial grade HVAC control boards are extremely similar.

Think of it this way. What's faster, stripping wire and shoving it in the back of an electric outlet, or stripping wire, curling it, sticking it under the screw on the side of the outlet, then using a screwdriver to tighten. When ppl get paid by the hour to do those menial tasks, its all about how fast it takes to get something done, and passed onto the next stage. It takes a machine 2 seconds to solder a molex to a board, it takes longer to have another machine first strip the ends of 24 different color wires, plus the machines to feed the wire from spools, dock workers to load the spools, overhead of wire costs, vrs a box of plastic molex, and further down the line someone grabs a pre-built mains and throws it in a bag with the other wires. On a mass scale, overall, full modular is cheaper. Only real reason why wired is still around is because the machines are still in serviceable use and have been for decades. That system isn't broke, so it don't need fixing, it's just not as cost effective per unit as full modular. That and OEMs don't get to pick who they want to build, vendors choose the OEM and OEM decides how cheap they can go and stay within the vendors specs.

Karadjgne,

You might be making these conclusions based on your experience in other industries, but for PSU manufacturing, you are incorrect on every single one of your assumptions.

No offense... I don't expect anyone else here to have worked as long in the PSU industry or have been to as many PSU factories as I have, but you're wrong.
