Running a rig built around an RX 480 would only need a *recommended* PSU wattage of 500W (which already includes the other basic components connected to that PSU). This wattage assumes that at the very least you are using a good quality and reliable PSU. Oftenly-linked reference to determine if your PSU quality is this Tier List: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

You want to select a Tier 1 or Tier 2 category PSU and would want to avoid if possible lower-tiered ones.

From your initial list (Corsair PSU's), both VS and CX / CXM series are categorized at Tier 4.

Tier Four
Built down to a low price. Not exactly the most stable units ever created. Very basic safety circuitry or even thin gauge wiring used. Not for gaming rigs or overclocking systems of any kind. Avoid unless your budget dictates your choice.

the Corsair CX(X) 450/550/650 are a newly updated line and far from the old unit. they're actually pretty decent.

also, the tier list is pretty old, out of date and "tiering" units is problematic.
for example the old CX and the VS were both Tier 4, but compared to the CX the VS is still junk, while the CX isn't really much worse than many Tier 3 units, will just break sooner.
Whilst the difference between the old Corsair RM and a Seasonic G is really substential although both are listed as Tier 2.

also the recommended Wattage for GPUs in no way assumes a quality PSU.
a non-overclockable i5-4570 draws no more than 84W, the Rx480 no more than 150, your total system draw won't exceed 300W. a 400W quality PSU could easily handle this for a decade, if there were one.

Sorry, but an RX480 has a "TYPICAL" board power of 150W (see this link: http://www.amd.com/en-us/products/graphics/radeon-rx-series/radeon-rx-480). It's not the Max. TDP. In fact, gaming tests have shown that it averages 164W (http://www.tomshardware.com/reviews/amd-radeon-rx-480-polaris-10,4616-9.html). Another fact that Sapphire RX 480 lists the power consumption at 225W (http://sapphirenitro.sapphiretech.com/en/480-8.html#specification) -- and futhermore, even recommends a 500W PSU. So why are you saying that the RX480 would draw "no more than 150"??


You MUST assume that the recommended wattage comes from a quality PSU. If the recommended wattage is 500W, and you are suggesting that the OP get a 450W PSU (50W lower than what's recommended) and, to top that, of inferior quality (to quote you: "CX isn't really much worse than many Tier 3 units, will just break sooner" -- then, I'm sorry, I have to disagree with you, as that is just bad advice.

OP, here's my honest to goodness assessment: I won't recommend ANY of the 3 choices you initially listed. But if you HAVE TO choose among these 3 and ONLY these 3, it is your own risk.

if the VS650 is the same price as the CXM450, going for the VS650 is just bad business.
all the additional wattage you don't use is just wasted and won't result in longer lifespan nor better performance
and while the VS650 might hold 2 years, the CXM450 comes with 5 years warranty

let it be 165W, although through the Christmas update, the Rx480s draw less power than initially. still not a problem.
as for 230W -- haven't seen any benchmark supporting that. 230W is usually total system draw, as seen

on Kitguru:

testing setup: Processor: Intel 6700K @ 4.4ghz
Memory: Corsair Vengeance LPX 16GB (2x8GB) @ 3000mhz
Motherboard: ASUS Z170-E DDR4 ATX Motherboard

on Eteknix:

Motherboard – Gigabyte X99-Gaming G1 WiFi LGA 2011-3 Motherboard
Processor – Intel Core i7 5820K at Stock 3.3GHz
RAM – 16GB (4 X 4GB) Crucial Ballistix Sport DDR4 2400MHz

or as the comparison tests on hardwareluxx.de (last 2 charts) or Computerbase.de (first chart) shows

you haven't read carefully. the 450/550/650W CX(M) are updated units that are far superior in quality and would be tiered Tier 2 in that list -- according to the units that are in that tier. it's an updated design with DC-DC converters, some better caps and better regulation. it's a strong contender against the Seasonic S12II and the XFX Core.
what I meant was that the OLD CX isn't much worse than many tier 3 units.

All that means absolutely nothing.
Recommended wattage they have no clue if I'm using a 65 watt processor or a 220 watt AMD processor.
Just because it has a 8 pin power connector and in theory could consume 225 watts means nothing also.
Total system power while gaming 221 watts using a overclocked 6700K.

Do a bit more research of power supplies the CXm450 is very acceptable quality it's on a bit newer platform from the CX 430, 500, 600 series.

It's the OP's decision. I don't recommend any of the 3 choices you listed. Others recommend the CX 450M as sufficient to run your i5-4570 + Sapphire RX 480 (despite the fact that both RealHardTechX and Sapphire themselves recommends 500W PSU). It's your call OP.
