Looking for a tier two 550w PSU with an above minimum hold up time

NetLiberate · Jun 14, 2016

Hi, my PC spec is FX 8350, R9 270x, 8GB RAM later this year i'm gonna upgrade to 6600k and a 1070 (or r9 480x). I'm not going to OC just gaming.

550w is enough, right?

Thanks!

NB : Can't find EVGA in my country

550w will drive that no problem. Seasonic should be available almost anywhere, the Seasonic S12II 520, or G series 550 will both do the job. Also the XFX TS 550 is basically the same.

there may be a review that covers hold up times but that's just milliseconds so its not a real big factor overall

[from toms hardware article]

Hold-Up Time—The amount of time (in milliseconds) that a power supply can maintain output within the specified voltage ranges after a loss of input power. This enables your PC to continue running without resetting or rebooting if a brief interruption in AC power occurs. Values of 15–30 milliseconds are common for today’s power supplies, and the higher (longer), the better. The Power Supply Design Guide for Desktop Platform Form Factors specification calls for a minimum of 16 ms hold-up time. The hold-up time is also greatly affected by the load on the power supply. The hold-up specification is normally listed as the minimum time measured under the maximum load. As the load is reduced, hold-up times should increase proportionately. For example, if a 1000 W PSU has a 20 ms hold-up time specification (measured under a 1000 W load), then under a 500 W (half) load I’d expect that to double, and under a 250 W load I’d expect it to double again. This is in fact one of the reasons I’ve always been a proponent of specifying higher output PSUs than are strictly necessary when building systems

so in the end statement a 850w should be better than a 550w ??

also all ways buy the best in build quality in a psu its the hart and life's blood of your build would you want a 2ed tier hart ???

good luck

My area got blackout like once a day for a few second randomly, so maybe a high hold up times would be better, right?

Get an RMX 550W.

^^Yep they have solid holdup time. Though you only need good holdup time to match your UPS, really. What's more important is that the PWR_OK signal drops before the voltages go out of spec.

like around here with our 3ed world power grid in the end I don't think it really matters it cant hurt but in the end ??? I'm already looking to replace another hard drive thanks to unstable power lines/ grid here in LA [lower Alabama ] if you live in a rural area like me your just doomed

as many hard drives I go through over the years I get to wondering if this aint the best bet over all over time ??

Thanks for all the reply!

EDIT : Unfortunately, RMX550w isn't available on my country... only 650w available and it's overkill for my spec... FX8350, R9 270x, 1 SSD, 1 HDD

So... I need other suggestion :/

Do you have a link to the store you would order from?

Ok so I see in that first link XFX TS Gold 550w and also Superflower Leadex Gold 550w, both are excellent choices.

In the second link the Seasonic S12G 550
