Greetings,
Looking at new PSUs to replace my aging Cooler Master Silent Pro M 1000w. Was just about to buy a EVGA superNOVA 1000 T2 due to all the positive talk about but the rail ratings stopped me wanting more info.
Especially looking at the +3.3v, +5, and +5VSB rails here are the comparisons with two PSUs im considering and my old Cooler Master.
Cooler Master Silent Pro M; +3.3V@30A, +5V@30A, +12V@80A, -12V@0.3A, +5VSB@3A
Corsair HXi 1000; +3.3V@25A, +5V@25A, +12V@83.3A, -12V@0.8A, +5VSB@3A
EVGA 1000 T2; +3.3V@20A, +5V@20A, +12V@83.3A, -12V@0.5A, +5VSB@2.5A
So compared I am losing 10amps on each the +3.3v and +5v rails, +5VSB is also 0.5amps lower which had some complains on reviews. Otherwise on similar units on the market the minor rails stay at 24A and above.
Is this that big of a deal? What runs on the 3.3 and 5v rails? What makes these minor rails important or are they not too important?
ALSO, noted on the superNOVA T2 the PSU cables are caps in them as well. If I replace them with cablemod sleeved cables will that affect Performance and/or Ripple Suppression to a worrisome degree?
My system:
Intel Core i7 4820K @ 3.9GHz, Asus Rampage IV Black Edition(X79), 16GB of G. Skill 2400MHz DDR3 10-12-12-31-2t (1.65v), EVGA GTX 780Ti, 2x Intel 730 480GB SSD in RAID 0, 1TB WD Caviar Black HDD, Asus Xonar Essence STX sound card, along with 2x optical drives(1 Blu-Ray), and 5 LED fans.
I am set of 1000watt PSUs for the space for future upgrades and OCs
