What tier(s) would the SeaSonic OEM PSUs be rated? I don't see them mentioned anywhere on the list.

Some models include (all say they're Haswell compatible):

80+ Bronze, 80mm fan:
SSP-350SE

80+ Bronze, 120mm fan:
SSP-300ST
SSP-350ST

80+ Gold, 120mm fan:
SSP-450RT
SSP-550RT
SSP-650RT

Examples that say they're not Haswell compatible (according to Newegg's specifications tab), or don't say:
SS-300ET Bronze
SS-350ET Bronze
SS-300ES Bronze
SS-400ET Bronze
SS-500ES Bronze
SS-500ET Bronze
SS-600ET


I found a few reviews (via realhardtechx.com) for a couple units, but nothing from JonnyGuru, TechPowerUp, Tom's Hardware, etc.

Of the reviews linked above (there were also a few discontinued units I didn't link), I'd personally only be considering the SSP-650RT. For a home/office PC with no discrete GPU (or at most, for power usage, a GTX 750 Ti or GT 720 - I wish there were some low-wattage Maxwell cards) and using a 65-watt or less CPU, in cases like the NZXT Source 210 Elite, Fractal Design Core 1500, Arc Mini R2, Corsair 100R, Cooler Master N300, etc, I'd be more interested in something like the SSP-300ST or SSP-350ST, as the SSP-650RT I think would be overkill for such a system.
 
I've used a few of those low-power Seasonics. Not to sound like a fanboy, but having never read a bad review of any Seasonic PSU, I suspect they are at least tier 3; probably better. I won't hesitate to use them in low-power builds.
 
Whether they are designed for high wattage, instantaneous power output like gaming psus are built for, or not, like the SS series, one thing is certain about Seasonic psus in general. The damn things are Solid across the board, which is a lot more than can be said about many other OEMs.
 
I want to change my CX500 for R9 380. Any suggestion? I was attracted to M12ii 620 Evo since it's only slightly different than CX500 (maybe $10), is this good a choice? Or maybe there is a better for same or better price
 


If you are going to upgrade to any Haswell or newer Intel chip, you don't want that PSU as it's not compatible with the C6/C7 low power states, unless you turn those off in the bios.

Better would be to get a unit that is Haswell compatible, and eliminate the issue altogether. The Seasonic 520 and 620w platforms are not Haswell compliant, and I don't believe any of the Antec or other brands who have models based on those platforms are either. I suppose it's possible some of the variants are, but I don't think so.

 


That is an ancient unit that has been long discontinued. That being said it's made by Seasonic and if it's new and sealed in a box is fine for an old Core2 system.
 
Hi guys, I'm back once again! My PC isn't here yet, but someone replied to my thread on the HP forums with a picture of the PSU (they had the same question I did about wattage).

http://h30434.www3.hp.com/t5/Desktop-Hardware/HP-ENVY-750xt-Desktop-PC-500-W-PSU-isn-t-enough/td-p/5373919/highlight/false

Specs of my PC:
•No Secondary HDD
•Microsoft Office Trial
•No Additional Security Software
•Home and Home Office Insert
•HP USB volume control Keyboard and USB Optical Mouse
•12GB DDR3-1600 DIMM (1x8GB+1x4GB) RAM
•7-in-1 Media Card Reader, 4 USB Ports (Top), Audio [Top 2USB2.0, 2USB3.0]
•Integrated Sound
•2TB 7200 RPM SATA 6G Hard Drive
•SuperMulti DVD Burner
•HP Wireless 802.11 a/b/g/n/ac 1x1 with Bluetooth M.2 NIC
•500W Power supply
•4th Generation Intel(R) Core(TM) i7-4790K processor quad-core [4.0GHz, 8MB Shared Cache]
•Windows 10 Home 64-bit OS
•6GB Nvidia GeForce GTX 980Ti [DL DVI-I, HDMI, DP, DP, DP]

The 500W PSU seems worrying, and I'm fairly certain that I'm going to need a new one. Here's an image of the psu, thanks to PinoyPower at the HP forum: http://imgur.com/GefHydb


An HP expert also replied to the thread with this:
"If you look close near the bottom left on the PSU it's rated at 500 watts max. Most NVIDIA 980 TIs are rated at 250 watts with a few going as high as 300 watts. Some require two PCIe 8 pin power connectors and some one PCIe 8 pin and one PCIe 6 pin power connectors. It's going to depend on the graphics card manufacturer as to the power requirements."

PinoyPower again, with more info on the video card:
"I know that HP uses reference GPU cards, so this has to be a Nvidia Geforce 980Ti. Which means that this requires one PCIe 8 pin and one PCIe 6 pin power connector. I was looking at the specs and I do see that its rated for 250W, but I also see that the minimum requirement is 600W."


So, I figured I'd come back here and ask you guys for a final verdict. Do I need to replace the PSU? If so, any recommendations at $100 or less from newegg would be fantastic! (Or I can reference the tier list)
 
Yeah, I'd replace any OEM PSU, esp one that runs a 980 and a i7... Really, anything tier 1 or 2 is good. Whatever fits in the case(if you plan to reuse it) and modular if possible since OEM cases are generally cramped as hell... My mistake was using a Seasonic TFX PSU with like 20 cords(It's a lot) and stuffing them all inside a pint-sized case....
 


So I found Power Supply - IPS,ATX,Picolit,500W,EStarBronze,5Vsb/4A using the Parts Number (746177-002) from the image here: http://h30434.www3.hp.com/t5/Desktop-Hardware/HP-ENVY-750xt-Desktop-PC-500-W-PSU-isn-t-enough/m-p/5395409/highlight/true#M106865

The unit this person received was a Delta unit rated for 500W max. I'm assuming that I'm probably going to get the same unit in mine, since we both ordered the same PC. I take it that this is probably an ATX form power supply, then? Should I still be aiming for 650W? Specs are posted two posts up that way^
 
I want to know more about this unit: http://www.amazon.com/Sentey%C2%AE-Mbp750-hm-Autoswitching-Certified-Warranty/dp/B00SN7CGAO
All I can find is this photo of the inside and it doesn't show much

This is a SUPER popular unit and on the outside the specs look decent. Big single rail, 4 8-pins, 5 year warranty and all. Sirtec has made some great and some trash units and I really want to know where this stands. Obviously it will not be awesome, I just want to know if it is coolmax,apex,allied,raidmax,etc. bad or just average.
