well quality of psu >>> quantity. 600w means nothing. A company will sell a 600w psu, and another will sell the exact same psu as 400w, it's very common (ie silencer 400w vs neo eco 620w).
For example, you got a thermaltake tr2. I dont know if you got the V1 or V2, but the V1 is so bad that it isn't even capable of ~400w. Remember, they also are rated for different temps. Corsair says the CX430 is rated for 430w@25C, but that's room temperature, and electronics never run room temp (or maybe you dont use AC), more like 50C. So real world power rating would be more like ~300-350w@50C. Then, the rosewill capstone 450w is rated for 50C, but it runs very cool so it's more like 500w@40C, not to mention it's been tested and shown to handle upwards of 600w just fine.
Then you got transience, how well and smoothly it goes from low voltage to high, efficiency, durability, ability to handle high temps, how much cooler it runs, and the fan used... a VR1 is so bad that you should literally throw it away, it's too low quality to overclock on. A VR2 is a really bad PSU too, but you can do an overclock on it... it's really, really bad though, most people would advice, strongly, against even using it.
I get a lot of 9c when messing with RAM or IMC, but it can come from CPU too. Make sure your RAM is downclocked while messing with your CPU overclock, to make sure it doesnt mess things up. Then, come back to it afterwards when you know for sure what's best for your cpu/vcore.
But you have an extremely low quality board, you literally have the 2nd worst motherboard possible on z77, so you'll be hard pressed to do a moderate overclock on that board, it really depends on how good your chip is. If your chip is average, ie 4.5-4.6ghz requires ~1.4v, then there is no way you are going to even do that on it.
As long as your CPU temp stays below 90C, you are good, but you picked out some really... bad, parts. i think everything but your cpu is really bad (not bad as in low end, bad as in horrible value and low quality at same time). Make sure to use HWInfo and monitor your VRM temps. If your board doesn't provide a VRM temps, then you need to use a thermal diode from a temp sensor, like an IR gun or a fan controller has thermal diodes usually, some cases do too.
Max vcore is 1.5v on Ivy, you are way below that. 4.6ghz tends to take, depending on chip quality, 1.2-1.45v, most chips needing ~1.4v (the majority of chips are binned poorly, ie 50-60% can only do 4.5-4.6ghz on reasoanble voltages). With water cooling you should be able to come pretty close to the max voltage even if you don't delid, which you should.
