Which PSU is better for my HP Pavilion HPE-580t?

Joseph DeGarmo · Jun 23, 2014

I'm looking to upgrade to a better quality PSU. My original PSU is dead and I'm down to just my Corsair CX600M which has had recent problems with loose plug connections or something. I want to upgrade to a more reliable PSU and use my current one as an emergency backup. Which should work better?

http://www.amazon.com/SeaSonic-550-Watt-CrossFire-Certified-SSR-550RM/dp/B00918MEZG/ref=sr_1_1?ie=UTF8&qid=1403551645&sr=8-1&keywords=seasonic+550w

Or is there a 600w gold-certified PSU which I overlooked?

Of the two, Seasonic is the better one. But at $20.00 less, I would get the Antec.

Dark Lord of Tech · Jun 23, 2014

Both of those PSU's are very high quality and they are OEM sized (5.5" x 5.9" x 3.4") which will make a perfect sized replacement for your hp.

Pick either one you can't go wrong.

So from I learned, SeaSonic is the king of PSUs. Is it better to get a gold-certified SeaSonic or a lesser brand at platinum level? Is there much difference between gold and platinum certified?

Dark Lord of Tech · Jun 23, 2014

Has nothing to do with performance get the cheaper one.

XFX TS Series P1550SXXB9 550W $36 after $25 rebate. It is also made by Seasonic for XFX and has 5 year warranty.

I own 3 of these so I have personal experience with these in HP desktops.

The XFX TS 550 fit in my HP p7-1436s, p6-2316s and hp p6516f although the cables get cumbersome.

Pondering :

Great find! I'm a bit skeptical about the bronze rating, though. I read somewhere that higher certifications are just more energy efficient. I've been suspecting that the certification rating makes a difference in the ability for a PSU to handle the full wattage levels. So is it better to get a 550w platinum or a 600w bronze? I saw a SeaSonic 620w bronze PSU somewhere. However, it seems as if my motherboard has difficulty handling higher-wattage PSUs. I once tried installing a 650w Corsair HX650 gold, but it would not boot up the PC. So would it be safer to go with either of the 550w models I posted earlier? I'm sure they can handle my configuration just fine. I want to upgrade to an 800-series Maxwell GPU and that series should be more energy efficient than the 600 series. I plan to stick with a single GPU rather than SLI. My CPU has a high TDP (130w), so will it still be safe to run, say, a GTX 870, in my rig with one of the 550w PSUs?

I may be thinking towards the Antec since I'm a Walmart employee and I get a 10% discount on general merchandise. So could this be my best option?

Dark Lord of Tech · Jun 24, 2014

Any of the above are great choices , the 80 Plus efficiency rating has nothing to do with performance , the money saved from bronze to platinum is minimal.

Dark Lord of Tech · Jun 24, 2014

The SEASONIC and XFX that went on SALE yesterday all use high quality Japanese caps , The Antec made by FSP uses poor quality secondary caps.

The Antec is still decent , but a step below the other 2.

Joseph DeGarmo · Jun 24, 2014

So will this work, then?

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151096

Dark Lord of Tech · Jun 24, 2014

Yes , very high quality supply also has all Japanese Caps.

Joseph DeGarmo · Jun 24, 2014

The wattage is a bit higher, but I'll look strongly into this one. I'm reading consumer reviews before deciding on this one.

Dark Lord of Tech · Jun 24, 2014

The only reason I'd stay away from the Antec is the lower quality secondary caps.

Joseph DeGarmo · Jun 24, 2014

Actually, I like this one better since it's modular.

Dark Lord of Tech · Jun 24, 2014

Great power supply , super solid choice definitely consider it.

Joseph DeGarmo · Jun 24, 2014

So will this definitely work on my PC although it's an older model running a socket LGA 1366 motherboard? Anyone with HP desktops have any issues with this one?

Dark Lord of Tech · Jun 24, 2014

The only thing that might be an issue is the length.

6.3" x 5.9" x 3.4"

I always recommend the XFX 550watt ANY VARIETY because they are OEM sized and fit in the prebuilts better , because of the shorter length.

5.5" x 5.9" x 3.4"

Dark Lord of Tech · Jun 24, 2014

Have to go to work good luck with your choice , have a great day\night.

Joseph DeGarmo · Jun 24, 2014

Oh, darn. My Corsair CX600M has the same dimensions as the XFX model. I'll have to look into that one, then, since the SeaSonic 620w looks like it will be too big.

Joseph DeGarmo · Jun 24, 2014

Pondering :

Is there a modular version of this one? Or will this one be perfectly fine? I'd hate to cram up my case.

Dark Lord of Tech · Jun 24, 2014

You won't find a decent modular one that size , get what fits.

OK, target selection is now locked in. I'll place the order for this shortly. Thanks! I don't plan on going too high-end on my next video card, so this should work. Hope this upgrade goes well.

Dark Lord of Tech · Jun 24, 2014

Hope it goes well , keep us posted!

Joseph DeGarmo · Jun 30, 2014

I received new PSU today, connected it, and all is good. The PSU swap is successful and now I have a better quality unit which I can safely depend on. Thanks for your help, guys!

Pondering · Jun 30, 2014

I ended up removing the optical drive to give myself more space for putting the extra cables however in the end, I ended up buying a mid tower case for $20 after rebate since the power supply could be bottom mounted. The ones that I ended up getting are the Cougar Solutions Black Steel and NZXT Source 210 (without the windowed panel). Mounting the power supply on the bottom allowed me to just lay out the wires on the bottom of the case.

Just don't forget to send in the rebate. Print out an invoice from newegg.com, cut out the UPC and staple it to the rebate form. Sign and date the rebate form. Take your time writing out the address on the the envelope.
