TX750 V2 vs G-550/650

post #1 of 6
Thread Starter 
So, PSUs are pretty important! Who knew?

After upgrading from my 5-year-old Q6600 w/ P5Q3 Deluxe to i5-4670K w/ Gigabyte GA-Z87X-UD3H, and neglecting to do anything about the old bargain bin Cooler Master 750w unit, I'm starting to see all sorts of funkiness.

For starters, the machine is VERY temperamental. Sometimes it'll just go into a power loop where it doesn't post. When I manage to get the system up, one of my monitors goes all glitchy when I try to run it at 1080p (like I did for the past year or so with no problems) and I'm getting BSODs on a fresh windows 7 install. I can only assume that all of this is related to my 5-year-old PSU.

Now that I've got my head screwed on straight and have done a little researching, I believe I have narrowed my replacement down to one of three models, but since I know next to squat about PSUs, I thought I would bounce it off this forum.

My rig is in my sig, but the meat and potatoes are as follows:

i5-4670K w/ GA-Z87X-UD3H & 16GB Ripjaws X (planning to OC CPU and RAM but not go crazy)
HD7950 (no plans to add 2nd) with 2x 22" monitors via HDMI and DVI. (will OC via Catalyst software if at all)
1x 240GB Kingston SSD, 2x Seagate 1TB 7200RPM
DVD, portable USB mixer (M-audio Mobile Pre), USB devices like ipods/androids every once in a while.
Corsair H50 loop w/ 2 fans on the rad and 4 case fans (somehow it's still fairly quiet).

The candidates:

Seasonic G-650 (or G-550) Modular 80PLUS Gold PSU

or

CORSAIR Enthusiast Series TX750 V2 750W

The Seasonic 650 is $25 CDN more than the 550 and the Corsair. All have solid reviews, from what I can see.

I have never owned a modular PSU before, so I don't know how valuable that feature is? Is there any benefit beyond cable management?

Your thoughts are greatly appreciated.

Modular PSUs are much easier to install and uninstall. If you upgrade to a PSU that uses identical modular cables, then you can keep all of your modular cables right where they are and just swap the PSU, but of course you will have to unplug the 24-pin motherboard (ATX12V) and the 8-pin CPU (EPS12V) power cables, but that's a lot easier than all of them.

 

Anyway, if you have no plans on adding a 2nd card, then get a good quality-made 450-550W PSU. The SeaSonic G Series is a very good choice. Are you able to order from Newegg.com?

I've never ordered from Newegg, but I notice that they have a Canadian site. I do most of my shopping at Canada Computers which tends to be fairly competitive in terms of pricing. The G-550 is currently listed at $100, and unfortunately, things are wonky enough that I don't think I can wait for a sale.

NCIX.ca is probably about the best. ;)

Looks like it's the same price at NCIX, but it's on backorder. Stock levels show 3 units at my local CC, so I'll probably just pop in there tomorrow on my way home from work and grab one.

Thanks for the reco!
